Struct CellMetrics 

pub struct CellMetrics {
    pub width_subpx: u32,
    pub height_subpx: u32,
}

Cell dimensions in sub-pixel units (1/256 px) for deterministic layout.

Both width_subpx and height_subpx must be > 0. Use CellMetrics::new to validate.

Fields

width_subpx: u32

Cell width in sub-pixel units (1/256 px).

height_subpx: u32

Cell height in sub-pixel units (1/256 px).

Implementations

impl CellMetrics

pub const MONOSPACE_DEFAULT: Self

Monospace terminal default: 8x16 px.

pub const LARGE: Self

Common 10x20 px cell size.

pub fn new(width_subpx: u32, height_subpx: u32) -> Option<Self>

Create cell metrics from sub-pixel values.

Returns None if either dimension is zero.

pub fn from_px(width_px: f64, height_px: f64) -> Option<Self>

Create cell metrics from floating-point pixel values.

Converts to sub-pixel units internally. Returns None on invalid input.

pub const fn width_px(&self) -> u32

Cell width in whole pixels (truncated).

pub const fn height_px(&self) -> u32

Cell height in whole pixels (truncated).

Trait Implementations

impl Clone for CellMetrics

fn clone(&self) -> CellMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CellMetrics

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

Formats the value using the given formatter.

impl Default for CellMetrics

fn default() -> Self

Returns the “default value” for a type.

impl Display for CellMetrics

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

Formats the value using the given formatter.

impl Hash for CellMetrics

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 PartialEq for CellMetrics

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