Trait Error

pub trait Error: Display {
    // Required methods
    fn custom<D: Display>(msg: D, codec: Codec) -> Self;

}

A generic error that can occur while decoding ASN.1. Caller needs always to pass a crate::Codec variant to Error when implementing the decoder

Required Methods

fn custom<D: Display>(msg: D, codec: Codec) -> Self

Creates a new general error using msg when decoding ASN.1.

fn incomplete(needed: Needed, codec: Codec) -> Self

Creates a new error about needing more data to finish parsing.

fn exceeds_max_length(length: BigUint, codec: Codec) -> Self

Creates a new error about exceeding the maximum allowed data for a type.

fn missing_field(name: &'static str, codec: Codec) -> Self

Creates a new error about a missing field.

fn no_valid_choice(name: &'static str, codec: Codec) -> Self

Creates a new error about being unable to match any variant in a choice.

fn field_error(name: &'static str, error: DecodeError, codec: Codec) -> Self

Creates a new error about being unable to decode a field in a compound type, such as a set or sequence.

fn duplicate_field(name: &'static str, codec: Codec) -> Self

Creates a new error about finding a duplicate field.

fn unknown_field(index: usize, tag: Tag, codec: Codec) -> Self

Create a new error about unknown field.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
