Struct PostingAlignment 

#[non_exhaustive]
pub struct PostingAlignment {
    pub number_col: usize,
    pub number_width: usize,
}

Pre-computed alignment data for a whole source file.

Bean-format-style two-axis alignment. The number field is a fixed-width slot starting at column number_col and number_width chars wide, into which each posting’s number / arithmetic expression is right-justified. Shorter numbers are left-padded with spaces, so the currency column (right after the field) is uniform across the whole file even when individual numbers have different widths or signs.

• number_col = INDENT + max(account width with optional flag ) + 2
• number_width = max rendered width of any posting’s number / arithmetic expression (sign included)

PostingAlignment is Copy and Default (the all-zero state); the default is the alignment used for files that contain no postings (no transactions, or transactions with no AMOUNT). Marked #[non_exhaustive] so that a future column-derivation rule can add fields without breaking downstream consumers.

Name choice. The type is qualified by its semantic purpose (posting layout column widths) so the public path rustledger_parser::format::PostingAlignment doesn’t compete with future generic “alignment” types (text justification, memory layout, etc.).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

number_col: usize

0-indexed column at which the right-justified number field starts.

number_width: usize

Width of the number field; shorter numbers are left-padded with spaces so the currency column stays uniform.

Trait Implementations

impl Clone for PostingAlignment

fn clone(&self) -> PostingAlignment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PostingAlignment

impl Debug for PostingAlignment

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

Formats the value using the given formatter.

impl Default for PostingAlignment

fn default() -> PostingAlignment

Returns the “default value” for a type.

impl Eq for PostingAlignment

impl PartialEq for PostingAlignment

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