Trait nom::error::ParseError [−][src]
This trait must be implemented by the error type of a nom parser.
There are already implementations of it for (Input, ErrorKind)
and VerboseError<Input>
.
It provides methods to create an error from some combinators,
and combine existing errors in combinators like alt
.
Required methods
fn from_error_kind(input: I, kind: ErrorKind) -> Self
[src]
Creates an error from the input position and an ErrorKind
fn append(input: I, kind: ErrorKind, other: Self) -> Self
[src]
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
Provided methods
fn from_char(input: I, _: char) -> Self
[src]
Creates an error from an input position and an expected character
fn or(self, other: Self) -> Self
[src]
Combines two existing errors. This function is used to compare errors generated in various branches of alt
