Struct GroupingStyle 

pub struct GroupingStyle<'a> { /* private fields */ }

How numerals are grouped, resolved per currency.

Copy on purpose: it is threaded as a sibling of PostingAlignment through the width pre-pass and the emitters, which must agree about a numeral’s width or the currency column drifts — the #1290 failure. It is NOT a field of PostingAlignment: that type is pub, Eq and cached on ParseResult, so it cannot carry a lifetime. The invariant that pairs a cached alignment with the style it was measured under is stated on format_node_with_style (crate-internal).

Implementations

impl<'a> GroupingStyle<'a>

pub fn from_context(ctx: &'a DisplayContext) -> Self

Grouping as declared by a ledger’s display context.

Returns the no-grouping style when the context groups nothing, so the overwhelmingly common case costs no per-numeral lookups.

pub const fn groups_anything(self) -> bool

Whether this style groups anything at all.

Lets a caller keep the fast precomputed-alignment path when nothing is declared, which is the overwhelming majority of ledgers.

pub fn groups(self, currency: Option<&str>) -> bool

Whether a numeral in currency is grouped. None for numerals with no currency in scope (metadata values, custom values), which take the ledger-wide default.
