Trait TagError

pub trait TagError<I, T>: Sized {
    // Required method
    fn from_tag(input: I, tag: T) -> Self;

    // Provided method
    fn from_tag_no_case(input: I, tag: T) -> Self { ... }
}

Similar to FromExternalError and ContextError, this trait allows a parser to create an error representing an unmatched tag. This allows error messages to produce more useful context about what went wrong.

Required Methods

fn from_tag(input: I, tag: T) -> Self

Create an error from an expected tag at a location.

Provided Methods

fn from_tag_no_case(input: I, tag: T) -> Self

As above, but for a case insensitive tag. By default this just calls from_tag

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.
