Struct CifWriteOptions 

pub struct CifWriteOptions { /* private fields */ }

Decisions that cannot be recovered from a lowered structure.

Implementations

impl CifWriteOptions

pub const fn new() -> Self

Starts with deterministic connection identifiers and no explicit block id.

A connection’s identifier is not retained by the bond graph, so a canonical file numbers its connections in order. The numbering carries no meaning of its own; Self::without_generated_connection_ids refuses instead for a caller that wants nothing invented.

pub const fn without_generated_connection_ids(self) -> Self

Refuses connectivity rather than numbering its connections.

pub fn with_extra_categories(self, text: impl Into<Box<str>>) -> Self

Appends already-rendered mmCIF categories to the output.

For metadata the generic structure keeps in a typed extension (assemblies, non-crystallographic operators, space group) that this crate cannot see. The text must hold complete categories and no data-block header.

pub fn extra_categories(&self) -> Option<&str>

Rendered categories appended by the caller.

pub fn with_block_id(self, block_id: impl Into<Box<str>>) -> Self

Uses this explicit data-block identifier instead of _entry.id.

pub const fn with_generated_connection_ids(self) -> Self

Allows deterministic _struct_conn.id values when connectivity exists.

This is the default; it re-enables the choice after Self::without_generated_connection_ids. The connection’s own conn_type_id travels with the bond and is written from it, so no class is chosen here.

pub fn block_id(&self) -> Option<&str>

The explicit data-block identifier, when one was chosen.
