Module nom::error

Error management

Parsers are generic over their error type, requiring that it implements the error::ParseError<Input> trait.

Structs

VerboseError

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

Enums

ErrorKind	indicates which parser returned an error
VerboseErrorKind	error context for VerboseError

Traits

ParseError

this trait must be implemented by the error type of a nom parser

Functions

append_error	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
context	create a new error from an input position, a static string and an existing error. This is used mainly in the context combinator, to add user friendly information to errors when backtracking through a parse tree
convert_error	transforms a VerboseError into a trace with input position information
error_to_u32	converts an ErrorKind to a number
make_error	creates an error from the input position and an ErrorKind
