Enum nom::verbose_errors::Context

pub enum Context<I, E = u32> {
    Code(I, ErrorKind<E>),
    List(Vec<(I, ErrorKind<E>)>),
}

Contains the error that a parser can return

If you use the verbose-errors compilation feature, nom::Err will be the enum defined here, otherwise, it will amount to a ErrorKind<E=u32>.

It can represent a linked list of errors, indicating the path taken in the parsing tree, with corresponding position in the input data. It depends on P, the input position (for a &u8 parser, it would be a &u8), and E, the custom error type (by default, u32)

Variants

Code(I, ErrorKind<E>)

An error code, represented by an ErrorKind, which can contain a custom error code represented by E

List(Vec<(I, ErrorKind<E>)>)

Methods

impl<I, E> Context<I, E>

pub fn into_error_kind(self) -> ErrorKind<E>

Convert Err into ErrorKind.

This allows application code to use ErrorKind and stay independent from the verbose-errors features activation.
