Enum iota_package_resolver::ErrorConstants

pub enum ErrorConstants {
    None,
    Rendered {
        identifier: String,
        constant: String,
    },
    Raw {
        identifier: String,
        bytes: Vec<u8>,
    },
}

The ErrorConstants enum is used to represent the different kinds of error information that can be returned from a clever error when looking at the constant values for the clever error. These values are either:

• None - No constant information is available, only a line number.
• Rendered - The error is a complete error, with an error identifier and constant that can be rendered in a human-readable format (see in-line doc comments for exact types of values supported).
• Raw - If there is an error constant value, but it is not a renderable type (e.g., a vector<address>), then it is treated as opaque and the bytes are returned.

Variants

None

No constant information is available, only a line number.

Rendered

The error is a complete error, with an error identifier and constant that can be rendered. The rendered string representation of the constant is returned only when the constant value is one of the following types:

• A vector of bytes convertible to a valid UTF-8 string; or
• A numeric value (u8, u16, u32, u64, u128, u256); or
• A boolean value; or
• An address value

Otherwise, the Raw bytes of the error constant are returned.

Fields

identifier: String

The name of the error constant.

constant: String

The value of the error constant.

Raw

If there is an error constant value, but ii is not one of the above types, then it is treated as opaque and the bytes are returned. The caller is responsible for determining how best to display the error constant in this case.

Fields

identifier: String

The name of the error constant.

bytes: Vec<u8>

The raw (BCS) bytes of the error constant.
