Struct CostSpec 

pub struct CostSpec(/* private fields */);

Bracketed cost annotation: {...} (per-unit), {#...} (per-unit + total), or {{...}} (total-only). Contents stay flat (phase 2.2c); accessors scan the children.

Implementations

impl CostSpec

pub fn is_total(&self) -> bool

Returns true iff the opener is {{ (total-cost form).

pub fn is_per_unit_plus_total(&self) -> bool

Returns true iff the opener is {# (per-unit + total form).

pub fn number(&self) -> Option<Number>

Cost number (first NUMBER child token).

pub fn currency(&self) -> Option<CurrencyName>

Cost currency (first CURRENCY child token).

pub fn date(&self) -> Option<Date>

Cost date (first DATE child token), if present.

pub fn label(&self) -> Option<StringLit>

Cost label (first STRING child token), if present.

pub fn is_merge(&self) -> bool

Returns true iff the opener is immediately followed by a * merge marker (e.g., {*} or {* 500 USD}). A STAR elsewhere in the cost spec is the multiplication operator (e.g., {500 * 2 USD}), NOT a merge marker; position matters.

Trait Implementations

impl AstNode for CostSpec

fn can_cast(kind: SyntaxKind) -> bool

Returns true iff kind is the wrapper’s expected node kind. Used by cast and by enum dispatch.

fn cast(syntax: SyntaxNode) -> Option<Self>

Wrap syntax if its kind matches; otherwise None.

fn syntax(&self) -> &SyntaxNode

The underlying CST node. text() reproduces the original bytes; children() / children_with_tokens() walk the tree.

impl Clone for CostSpec

fn clone(&self) -> CostSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CostSpec

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

Formats the value using the given formatter.

impl Eq for CostSpec

impl Hash for CostSpec

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 CostSpec

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