Struct gstreamer_video::Error

pub struct Error(_);

A generic error capable of representing various error domains (types).

Methods

impl Error

pub fn new<T>(error: T, message: &str) -> Error where     T: ErrorDomain,

Creates an error with supplied error enum variant and message.

pub fn is<T>(&self) -> bool where     T: ErrorDomain,

Checks if the error domain matches T.

pub fn kind<T>(&self) -> Option<T> where     T: ErrorDomain,

Tries to convert to a specific error enum.

Returns Some if the error belongs to the enum's error domain and None otherwise.

Examples

if let Some(file_error) = error.kind::<FileError>() {
    match file_error {
        FileError::Exist => ...
        FileError::Isdir => ...
        ...
    }
}

match error {
    Some(FileError::Exist) => ...
    Some(FileError::Isdir) => ...
    ...
}

pub fn wrap(ptr: *mut GError) -> Error

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Error for Error

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&Error>

The lower-level cause of this error, if any.

impl Ord for Error

fn cmp(&self, other: &Error) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

impl PartialOrd<Error> for Error

fn partial_cmp(&self, other: &Error) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Error) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Error) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Error) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Error) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
