Enum FormatConversionResult 

pub enum FormatConversionResult<F> {
    Direct(F),
    Convert {
        from: F,
        to: F,
        cost: u32,
    },
    Incompatible,
}

Result of a FormatNegotiator negotiation run.

Discriminates between a direct match (no conversion needed), a conversion with an associated cost ordinal, and a fully incompatible pair.

Examples

use oximedia_core::codec_negotiation::{FormatNegotiator, FormatConversionResult};
use oximedia_core::types::PixelFormat;

let neg = FormatNegotiator::<PixelFormat> {
    decoder_produces: &[PixelFormat::Yuv420p],
    encoder_accepts: &[PixelFormat::Yuv420p],
};
assert_eq!(neg.negotiate(), FormatConversionResult::Direct(PixelFormat::Yuv420p));

Variants

Direct(F)

Encoder directly accepts what the decoder produces — no conversion needed.

Convert

A conversion is required. cost is an ordinal (0 = identity, higher = more expensive).

Fields

from: F

The format the decoder produces.

to: F

The format the encoder accepts.

cost: u32

Conversion cost ordinal.

Incompatible

No compatible conversion path exists.

Trait Implementations

impl<F: Clone> Clone for FormatConversionResult<F>

fn clone(&self) -> FormatConversionResult<F>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: Debug> Debug for FormatConversionResult<F>

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

Formats the value using the given formatter.

impl<F: PartialEq> PartialEq for FormatConversionResult<F>

fn eq(&self, other: &FormatConversionResult<F>) -> 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.
