Struct EmitCtx 

pub struct EmitCtx { /* private fields */ }

The site an emitted fragment will be spliced into.

Built by the insertion mutators from the document’s own detected conventions (Document::indent_unit, Document::dominant_quote_style, Document::dominant_flow_style) plus the column the new entry starts at, so an Emit implementation can match the file it is landing in rather than a serializer default.

Examples

use noyalib::cst::{Emit, EmitCtx};
use noyalib::{FlowStyle, ScalarStyle};

let ctx = EmitCtx::new(ScalarStyle::Plain, FlowStyle::Block, 2, 0);
// Plain is safe here, and the site prefers plain.
assert_eq!("noyalib".emit(&ctx).unwrap(), "noyalib");
// Plain would re-parse as a boolean — quoting is forced.
assert_eq!("true".emit(&ctx).unwrap(), "\"true\"");

Implementations

impl EmitCtx

pub fn new( quote: ScalarStyle, flow: FlowStyle, indent_unit: usize, column: usize, ) -> Self

Build a context from a site’s conventions.

column is the zero-based column the emitted entry starts at — the mapping key’s column, or the - indicator’s column for a sequence item.

It is advisory: an emitted fragment indents its own continuation lines relative to its first line, and the mutator shifts the whole fragment to the site’s content column afterwards. column is there for implementations that need to know where they land anyway — line-width budgets, for instance — not as the indent to emit at.

pub fn quote_style(&self) -> ScalarStyle

The dominant scalar quote style at this site.

pub fn flow_style(&self) -> FlowStyle

The dominant collection style at this site.

pub fn indent_unit(&self) -> usize

The document’s detected indent step, in spaces.

pub fn column(&self) -> usize

The zero-based column the emitted entry starts at.
