Struct DataUrl 

pub struct DataUrl { /* private fields */ }

A URL using the “data” scheme, according to RFC2397.

Implementations

impl DataUrl

pub const fn as_str(&self) -> &str

Return the string representation of this DataUrl.

pub fn parse(input: &str) -> Result<DataUrl, InvalidDataUrl>

Parses a DataUrl from the given string input.

Example

let data_url = DataUrl::parse("data:text/plain;base64,SGVsbG8sIFdvcmxkIQ==")?;
assert!(data_url.is_base64());
assert_eq!(data_url.media_type(), "text/plain");
assert_eq!(data_url.encoded_data(), "SGVsbG8sIFdvcmxkIQ==");

pub const fn is_base64(&self) -> bool

Returns whether this DataUrl has its base64 flag set, e.g. “data:image/gif”.

pub fn encoded_data(&self) -> &str

Returns the string representation of the data encoded within this DataUrl.

pub fn media_type(&self) -> &str

Returns the string representation of the MIME type of the data encoded within this DataUrl. The returned string also contains the type’s parameters if any.

Notes

When a DataUrl omits the MIME type (e.g. “data:,A%20brief%20note”), this method returns the default MIME type “text/plain;charset=US-ASCII”, instead of the empty string.

Example

Trait Implementations

impl AsRef<str> for DataUrl

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for DataUrl

fn clone(&self) -> DataUrl

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataUrl

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DataUrl

fn deserialize<D>( deserializer: D, ) -> Result<DataUrl, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DataUrl

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<DataUrl> for Url

fn from(data_url: DataUrl) -> Url

Converts to this type from the input type.

impl From<VcDataUrl> for DataUrl

fn from(value: VcDataUrl) -> DataUrl

Converts to this type from the input type.

impl FromStr for DataUrl

type Err = InvalidDataUrl

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<DataUrl, <DataUrl as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for DataUrl

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DataUrl

fn cmp(&self, other: &DataUrl) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DataUrl

fn eq(&self, other: &DataUrl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for DataUrl

fn partial_cmp(&self, other: &DataUrl) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for DataUrl

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<DataUrl> for VcDataUrl

type Error = InvalidMediaType

The type returned in the event of a conversion error.

fn try_from( value: DataUrl, ) -> Result<VcDataUrl, <VcDataUrl as TryFrom<DataUrl>>::Error>

Performs the conversion.
