Module `error`

Error management

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

Structs

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
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]
