Module nom::error[−][src]

Error management

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

Structs

default error type, only contains the error’ location and code

Indicates which parser returned an error

ContextError	This trait is required by the `context` combinator to add a static string to an existing error
FromExternalError	This trait is required by the map_res combinator to integrate error types from external functions, like [std::str::FromStr]
ParseError	This trait must be implemented by the error type of a nom parser.

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
error_to_u32	Converts an ErrorKind to a number
make_error	Creates an error from the input position and an ErrorKind
