Struct nom::error::VerboseError

source ·
pub struct VerboseError<I> {
    pub errors: Vec<(I, VerboseErrorKind)>,
}
Expand description

This error type accumulates errors and their position when backtracking through a parse tree. With some post processing (cf examples/json.rs), it can be used to display user friendly error messages

Fields§

§errors: Vec<(I, VerboseErrorKind)>

List of errors accumulated by VerboseError, containing the affected part of input data, and some context

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()
1.0.0 · source§

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

source§

fn from_error_kind(input: I, kind: ErrorKind) -> Self

Creates an error from the input position and an ErrorKind
source§

fn append(input: I, kind: ErrorKind, other: Self) -> Self

Combines an existing error with a new one created from the input position and an ErrorKind. This is useful when backtracking through a parse tree, accumulating error context on the way
source§

fn from_char(input: I, c: char) -> Self

Creates an error from an input position and an expected character
source§

fn or(self, other: Self) -> Self

Combines two existing errors. This function is used to compare errors generated in various branches of alt.

impl<I: PartialEq> PartialEq for VerboseError<I>

source§

fn eq(&self, other: &VerboseError<I>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
