Struct BaselineGrid 

pub struct BaselineGrid {
    pub interval_subpx: u32,
    pub offset_subpx: u32,
}

Baseline grid alignment configuration.

When active, line positions are snapped to a regular vertical grid to maintain consistent vertical rhythm. This is essential for multi-column layouts where lines should align across columns.

Fields

interval_subpx: u32

Grid interval in sub-pixel units.

All line positions are rounded up to the nearest multiple of this value. Typically set to the line height (line_height + leading).

offset_subpx: u32

Offset from the top of the text area (sub-pixel units).

Shifts the grid to align with an arbitrary starting position.

Implementations

impl BaselineGrid

pub const NONE: Self

No baseline grid (disabled).

pub const fn from_line_height( line_height_subpx: u32, leading_subpx: u32, ) -> Self

Create a grid from line height and leading.

pub const fn is_active(&self) -> bool

Whether the grid is active (non-zero interval).

pub const fn snap(&self, pos_subpx: u32) -> u32

Snap a vertical position to the grid.

Rounds up to the nearest grid line at or above pos.

Trait Implementations

impl Clone for BaselineGrid

fn clone(&self) -> BaselineGrid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BaselineGrid

impl Debug for BaselineGrid

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

Formats the value using the given formatter.

impl Default for BaselineGrid

fn default() -> Self

Returns the “default value” for a type.

impl Eq for BaselineGrid

impl Hash for BaselineGrid

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 BaselineGrid

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