    row_line_name_pairs: Vec<(u32, S)>,
}

Resolver that takes grid lines names and area names as input and can then be used to resolve line names of grid placement properties into line numbers.

Fields

row_lines: HashMap<StrHasher<S>, SmallVec<[u32; 4]>, RandomState>

Map of row line names to line numbers. Each line name may correspond to multiple lines so we store a SmallVec

column_lines: HashMap<StrHasher<S>, SmallVec<[u32; 4]>, RandomState>

Map of column line names to line numbers. Each line name may correspond to multiple lines so we store a SmallVec

areas: HashMap<StrHasher<S>, AreaLines, RandomState>

Map of area names to the lines of the area’s edges

area_column_count: u16

Number of columns implied by grid area definitions

area_row_count: u16

Number of rows implied by grid area definitions

explicit_column_count: u16

The number of explicit columns in the grid. This is an input to the NamedLineResolver and is used when computing the fallback line when a non-existent named line is specified.

explicit_row_count: u16

The number of explicit rows in the grid. This is an input to the NamedLineResolver and is used when computing the fallback line when a non-existent named line is specified.

column_line_name_pairs: Vec<(u32, S)>

The (1-indexed line number, name) pairs of every column line named in the track template, in source order (excludes the implicit names generated by grid-template-areas)

row_line_name_pairs: Vec<(u32, S)>

The (1-indexed line number, name) pairs of every row line named in the track template, in source order (excludes the implicit names generated by grid-template-areas)

Implementations

impl<S: CheapCloneStr> NamedLineResolver<S>

pub(crate) fn new( style: &impl GridContainerStyle<CustomIdent = S>, column_auto_repetitions: u16, row_auto_repetitions: u16, ) -> Self

Create and initialise a new NamedLineResolver

pub(crate) fn detailed_line_names(&self, axis: AbsoluteAxis) -> GridLineNames<S>

Build the per-line name groups of the explicit grid in the passed axis as a GridLineNames, with repeat()s expanded. Only names given explicitly in the track template are included; the implicit <name>-start/<name>-end names generated by grid-template-areas are omitted (matching the resolved value of grid-template-rows/grid-template-columns in browsers) but remain resolvable for placement via GridLineNames::resolve_line_names.

Line indices are relative to the explicit grid (line 0 = start of the first explicit track).

pub(crate) fn resolve_row_names( &self, line: &Line<GridPlacement<S>>, ) -> Line<GenericGridPlacement<GridLine>>

Resolve named lines for both the start and end of a row-axis grid placement

pub(crate) fn resolve_column_names( &self, line: &Line<GridPlacement<S>>, ) -> Line<GenericGridPlacement<GridLine>>

Resolve named lines for both the start and end of a column-axis grid placement

pub(crate) fn resolve_line_names( &self, line: &Line<GridPlacement<S>>, axis: GridAreaAxis, ) -> Line<GenericGridPlacement<GridLine>>

Resolve named lines for both the start and end of a grid placement

pub(crate) fn populate_detailed_line_resolvers( self, rows: &mut GridLineNames<S>, columns: &mut GridLineNames<S>, ) -> HashMap<StrHasher<S>, AreaLines, RandomState>

Move the row and column line-name maps into the detailed grid information, and return the grid area map for the same purpose

pub(crate) fn area_column_count(&self) -> u16

Get the number of columns defined by the grid areas

pub(crate) fn area_row_count(&self) -> u16

Get the number of rows defined by the grid areas

pub(crate) fn set_explicit_column_count(&mut self, count: u16)

Set the number of columns in the explicit grid

pub(crate) fn set_explicit_row_count(&mut self, count: u16)

Set the number of rows in the explicit grid

Formats the value using the given formatter.
