Module rocket::mtls::oid::asn1_rs::nom::error

Available on crate feature mtls only.

Error management

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

Structs

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

• 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
• convert_error
  Transforms a VerboseError into a trace with input position information
• 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
