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§
- Error
Kind - Indicates which parser returned an error
Traits§
- Context
Error - This trait is required by the
context
combinator to add a static string to an existing error - From
External Error - This trait is required by the
map_res
combinator to integrate error types from external functions, like std::str::FromStr - Parse
Error - 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
