Struct NamedLineResolver

pub(crate) struct NamedLineResolver<S: CheapCloneStr> {
    row_lines: HashMap<StrHasher<S>, Vec<u16>, RandomState>,
    column_lines: HashMap<StrHasher<S>, Vec<u16>, RandomState>,
    areas: HashMap<StrHasher<S>, GridTemplateArea<S>, RandomState>,
    area_column_count: u16,
    area_row_count: u16,
    explicit_column_count: u16,
    explicit_row_count: u16,
}

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>, Vec<u16>, RandomState>

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

column_lines: HashMap<StrHasher<S>, Vec<u16>, RandomState>

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

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

Map of area names to area definitions (start and end lines numbers in each axis)

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.
