Enum VideoResolution 

pub enum VideoResolution {
    Native,
    IntegerScale(u32),
    Hd720,
    Hd1080,
    Uhd4k,
    Custom(u32, u32),
}

Target video resolution for output.

Variants

Native

Native resolution (256x240 for NES)

IntegerScale(u32)

Integer scale (2x, 3x, 4x, etc.)

Hd720

720p (1280x720) - fit within bounds

Hd1080

1080p (1920x1080) - fit within bounds

Uhd4k

4K (3840x2160) - fit within bounds

Custom(u32, u32)

Custom resolution

Implementations

impl VideoResolution

pub fn parse(s: &str) -> Result<Self, String>

Parse a video resolution string.

Supported formats:

• “native” - Native resolution
• “2x”, “3x”, “4x” - Integer scales
• “720p”, “1080p”, “4k” - Standard resolutions
• “WxH” or “WIDTHxHEIGHT” - Custom resolution (e.g., “1920x1080”)

pub fn dimensions(&self, src_width: u32, src_height: u32) -> (u32, u32)

Calculate the output dimensions for a given source size.

For preset resolutions (720p, 1080p, 4k), the output is scaled to fit within the target while maintaining aspect ratio with the NES PAR (8:7).

Trait Implementations

impl Clone for VideoResolution

fn clone(&self) -> VideoResolution

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VideoResolution

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

Formats the value using the given formatter.

impl PartialEq for VideoResolution

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