Trait ContextError

pub trait ContextError<I, C>: Sized {
    // Required method
    fn add_context(location: I, ctx: C, other: Self) -> Self;
}

Updated version of nom::error::ContextError. Allows for arbitrary context types, rather than requiring &'static str

Required Methods

fn add_context(location: I, ctx: C, other: Self) -> Self

Create a new error from an input position, a context, and an existing error. This is used by the .context combinator to add friendly information to errors when backtracking through a parse tree.

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.
