Enum png::decoder::SubframeIdx

enum SubframeIdx {
    Initial,
    Some(u32),
    End,
}

Denote a frame as given by sequence numbers.

Variants

Initial

The initial frame in an IDAT chunk without fcTL chunk applying to it. Note that this variant precedes Some as IDAT frames precede fdAT frames and all fdAT frames must have a fcTL applying to it.

Some(u32)

An IDAT frame with fcTL or an fdAT frame.

End

The past-the-end index.

Trait Implementations

impl Clone for SubframeIdx

fn clone(&self) -> SubframeIdx

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SubframeIdx

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

Formats the value using the given formatter.

impl Ord for SubframeIdx

fn cmp(&self, other: &SubframeIdx) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for SubframeIdx

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for SubframeIdx

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

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

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

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

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

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

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

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

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

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