Enum SourceRetention 

pub enum SourceRetention {
    Retain,
    DropText,
    DropAll,
}

Source buffer retention policy

Controls memory vs. error reporting trade-off:

• Retain: Full source text available (~200KB per 200KB schema)
• DropText: Only line starts (~10KB per 200KB schema, 90% savings)
• DropAll: No location info (minimal memory)

Variants

Retain

Keep source text for rich errors and XmlFragment access

DropText

Drop source text after parsing; keep only line_starts

DropAll

Drop entire SourceMap after parsing; no location info

Trait Implementations

impl Clone for SourceRetention

fn clone(&self) -> SourceRetention

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SourceRetention

impl Debug for SourceRetention

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

Formats the value using the given formatter.

impl Default for SourceRetention

fn default() -> SourceRetention

Returns the “default value” for a type.

impl Eq for SourceRetention

impl PartialEq for SourceRetention

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