Enum RcMode 

pub enum RcMode {
    Cbr,
    Vbr,
    Crf,
    Qp,
}

Rate-control mode for a video encoder.

Note: a BitrateMode type already exists in the traits module; this enum is a standalone model-level counterpart with richer semantics.

Variants

Cbr

Constant Bitrate — output bitrate is held at a fixed target.

Vbr

Variable Bitrate — bitrate varies within min/max bounds.

Crf

Constant Rate Factor — quality-based encoding (e.g. x264 CRF).

Qp

Constant Quantisation Parameter — fixed QP per frame.

Implementations

impl RcMode

pub fn is_quality_based(self) -> bool

Returns true for quality-based modes (CRF, QP) where the encoder controls quality rather than a hard bitrate target.

pub fn is_bitrate_constrained(self) -> bool

Returns true for throughput-constrained modes (CBR, VBR).

pub fn label(self) -> &'static str

A short string label for the mode.

Trait Implementations

impl Clone for RcMode

fn clone(&self) -> RcMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RcMode

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

Formats the value using the given formatter.

impl PartialEq for RcMode

fn eq(&self, other: &RcMode) -> 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.
