Error management

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

Structs§

Context
Parser implementation for context
Error
default error type, only contains the error’s location and code

Enums§

ErrorKind
Indicates which parser returned an error

Traits§

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.

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
dbg_dmp
Prints a message and the input if the parser fails.
error_to_u32
Converts an ErrorKind to a number
make_error
Creates an error from the input position and an ErrorKind
