Struct AVIOInterruptCB 

#[repr(C)]
pub struct AVIOInterruptCB {
    pub callback: Option<unsafe extern "C" fn(arg1: *mut c_void) -> c_int>,
    pub opaque: *mut c_void,
}

Callback for checking whether to abort blocking functions. AVERROR_EXIT is returned in this case by the interrupted function. During blocking operations, callback is called with opaque as parameter. If the callback returns 1, the blocking operation will be aborted.

No members can be added to this struct without a major bump, if new elements have been added after this struct in AVFormatContext or AVIOContext.

Fields

callback: Option<unsafe extern "C" fn(arg1: *mut c_void) -> c_int>

opaque: *mut c_void

Trait Implementations

impl Clone for AVIOInterruptCB

fn clone(&self) -> AVIOInterruptCB

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AVIOInterruptCB

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

Formats the value using the given formatter.

impl Default for AVIOInterruptCB

fn default() -> Self

Returns the “default value” for a type.

impl Hash for AVIOInterruptCB

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for AVIOInterruptCB

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AVIOInterruptCB

fn eq(&self, other: &AVIOInterruptCB) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for AVIOInterruptCB

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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