Struct StyleRules 

pub struct StyleRules { /* private fields */ }

An ordered set of StyleRules. Where several match, their styles combine in order, a later rule winning wherever both set something.

Implementations

impl StyleRules

pub fn new() -> Self

No rules.

pub fn rule(self, rule: StyleRule) -> Self

Add a rule (builder form).

pub fn push(&mut self, rule: StyleRule) -> &mut Self

Add a rule.

pub fn rules(&self) -> &[StyleRule]

The rules, in order.

pub fn len(&self) -> usize

The number of rules.

pub fn is_empty(&self) -> bool

Whether there are no rules.

pub fn resolve<'a, R>( &'a self, headers: &[&str], rows: impl IntoIterator<Item = R>, ) -> ResolvedRules<'a>

where R: AsRef<[Value]>,

Resolve the rules against a table’s headers and rows: each rule’s column, and the styles of column rules (which need every row, so the rows are only read when a column rule exists).

impl StyleRules

pub fn from_toml(text: &str) -> Result<Self, RuleError>

Read the [[rules]] tables of a TOML document. See the module docs for the keys.

pub fn from_toml_value(value: &Value) -> Result<Self, RuleError>

Read rule tables from an array of tables, wherever a configuration keeps them (a profile’s rules key, say).

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

Performs copy-assignment from source.

impl Debug for StyleRules

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

Formats the value using the given formatter.

impl Default for StyleRules

fn default() -> Self
