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 positionsition 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
