FieldsSource

Struct FieldsSource 

Source
pub struct FieldsSource<'d> { /* private fields */ }
Expand description

Original schema-selected CONTENTS with their producing field depth. This small borrowed context survives a counter-walk frame’s parsed model and is also shared by CMS certificate/revocation field readers.

Implementations§

Source§

impl<'d> FieldsSource<'d>

Source

pub fn reader_in<'operation, W: Work>( &self, work: &'operation W, ) -> Result<ScopedReader<'d, 'operation>>
where 'd: 'operation,

Opens original fields, not a fabricated outer SEQUENCE. All current operation and original session/depth ceilings apply before decoding.

Source

pub fn query_in<'query>( &self, operation: &Reader<'query>, ) -> Result<Reader<'query>>
where 'd: 'query,

Opens a producing-reader query for models retaining original source readers. Unlike a callback-local Work borrow, the query’s source budget already has the document lifetime. Current operation funding and the actual original depth/session remain enforced by the SAME bridge.

Source

pub fn as_bytes(self) -> &'d [u8] ⓘ

Original field octets, without a synthesized SEQUENCE header.

Source

pub fn depth(self) -> u32

Actual original field depth, not an outer-reader approximation.
