Struct ErrorState 

pub struct ErrorState { /* private fields */ }

The error state a file or value handle carries.

asdf_error hands out a borrowed pointer into message, so the string must outlive the call and stay put until the next error is recorded.

Implementations

impl ErrorState

pub fn set(&self, code: i32, message: impl Into<Vec<u8>>)

Record an error.

pub fn set_system(&self, errnum: i32)

Record an OS-level error, deriving the message from strerror.

pub fn set_error(&self, err: &Error)

Record an engine error.

pub fn clear(&self)

Clear any recorded error.

pub fn code(&self) -> i32

The recorded code.

pub fn errno(&self) -> i32

The recorded errno, meaningful only for ErrorCode::System.

pub fn message_ptr(&self) -> *const c_char

A pointer to the recorded message, valid until the next error is set.

Safety

The returned pointer borrows from self and is invalidated by any later set/clear on the same state.

Trait Implementations

impl Debug for ErrorState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ErrorState

fn default() -> ErrorState

Returns the “default value” for a type.
