Struct TransactionFlag 

pub struct TransactionFlag { /* private fields */ }

Typed wrapper for the transaction-header flag token.

May be STAR (*), PENDING_KW (!), FLAG (letter), HASH (#), TXN_KW (txn), or single-character CURRENCY (ticker-letter flag, e.g. T). Use Self::classify for exhaustive match ergonomics, or the is_* predicates for boolean checks.

Note: Self::cast is position-AGNOSTIC — it accepts any token of a flag-eligible kind regardless of where it sits in the tree. To get the leading flag of a transaction, use Transaction::flag (which scopes the search to the pre-content header region).

Implementations

impl TransactionFlag

pub fn cast(token: SyntaxToken) -> Option<Self>

Wrap the token if its kind is a valid transaction flag. For CURRENCY, only single-character forms qualify.

Single source of truth: this match also derives Self::classify’s result, so cast + classify cannot drift.

pub const fn syntax(&self) -> &SyntaxToken

pub fn kind(&self) -> SyntaxKind

pub fn text(&self) -> &str

pub const fn classify(&self) -> TransactionFlagKind

Exhaustive classification — pair with a match for compiler-checked coverage of every variant. Cached at cast() time; no runtime panic risk.

pub const fn is_star(&self) -> bool

pub const fn is_pending(&self) -> bool

pub const fn is_hash(&self) -> bool

pub const fn is_txn(&self) -> bool

pub const fn is_letter_flag(&self) -> bool

pub const fn is_currency_letter(&self) -> bool

Trait Implementations

impl Clone for TransactionFlag

fn clone(&self) -> TransactionFlag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionFlag

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

Formats the value using the given formatter.

impl Eq for TransactionFlag

impl Hash for TransactionFlag

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 TransactionFlag

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