Struct SourceSpan 

pub struct SourceSpan {
    pub start: u64,
    pub end: u64,
    pub file_id: u16,
}

Source-location metadata for a posting that the host parsed from a beancount file.

Plugins receive this on every parser-derived posting and must preserve it unchanged when modifying an existing posting (the default for a typical “edit one field” plugin). When a plugin synthesizes a brand-new posting, leave PostingData::span as None and the host will mark it SYNTHESIZED_FILE_ID.

Byte offsets are stored as u64 so the wire format is stable across 32-bit (WASM) and 64-bit (host) targets, and so very large concatenated source trees (includes-of-includes) cannot silently overflow. The contents are otherwise opaque to plugin code: do not synthesize spans by guessing offsets.

Fields

start: u64

Start byte offset within the file (inclusive).

end: u64

End byte offset within the file (exclusive).

file_id: u16

Source file index in the host’s source map.

Trait Implementations

impl Clone for SourceSpan

fn clone(&self) -> SourceSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SourceSpan

impl Debug for SourceSpan

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SourceSpan

fn deserialize<__D>( __deserializer: __D, ) -> Result<SourceSpan, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SourceSpan

impl PartialEq for SourceSpan

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

impl Serialize for SourceSpan

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
