Module pwd_grp::error

Error handling and error types

Most of the interfaces return a std::io::Error. Usually an error means that the underlying get*_r call failed.

But, there are some other obscure error cases. In those situations, an io::Error will be returned which has one of the errors in this module as its source.

Structs

• NonUtf8Error
  Error that occurs if non-UTF-8 data is found
• TooLargeBufferRequiredError
  Error that occurs if an entry is unreasonably large
• UnexpectedNullPointerError
  Error that occurs if getpw*_r or getgr*_r return unexpected NULLs

Type Definitions

• NulError
  Error that occurs if a nul byte was passed to get*_nam
