Struct CanonicalProjection 

pub struct CanonicalProjection<'a> { /* private fields */ }

A validated semantic projection that can be consumed without text or a DOM.

Implementations

impl<'a> CanonicalProjection<'a>

pub const fn block_id(self) -> &'a str

The validated data-block identifier.

pub const fn structure(self) -> &'a Structure

The immutable semantic structure behind this projection.

pub const fn options(self) -> &'a CifWriteOptions

The explicit canonical decisions used for this projection.

pub fn sequence_references(self) -> Option<&'a SequenceReferences>

Database sequence references retained by the structure.

pub fn atom_site_row_count(self) -> Result<usize, CifWriteError>

Number of rows emitted by the atom-site category.

Errors

Returns a range refusal if the product or ragged-model sum exceeds usize.

pub fn carries_formal_charge(self) -> bool

Whether any atom carries a stated formal charge.

pub fn visit_atom_rows( self, visit: impl for<'row> FnMut(CanonicalAtomRow<'row>), ) -> Result<(), CifWriteError>

Visits canonical atom-site rows in deposition and model order.

The row borrows a model snapshot and is valid only for the synchronous callback. Replaying the visit is allocation-free and supports encoders that materialise only one output column at a time.

Errors

Returns a canonical write refusal if the immutable structure cannot supply a required row identity.

Trait Implementations

impl<'a> Clone for CanonicalProjection<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for CanonicalProjection<'a>

impl<'a> Debug for CanonicalProjection<'a>

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

Formats the value using the given formatter.
