Struct ConstructorBuilder 

pub struct ConstructorBuilder { /* private fields */ }

Accumulates a constructor definition and installs it via def_constructor.

Implementations

impl ConstructorBuilder

pub fn new(proto: &str) -> Result<Self>

Parse the prototype (shared with the macro path via parse_prototype).

pub fn replacement(self, repl: ReplacementClosure) -> Self

Set the XML replacement (template- or closure-derived; built by the caller).

pub fn set_option(self, key: &str, value: OptionValue) -> Result<Self>

Apply a scalar option by name (see apply_scalar_option, the single-source key→field map shared with EnvironmentBuilder).

pub fn after_digest(self, hook: DigestionClosure) -> Self

Push an afterDigest hook (constructor: after digestion; environment: runs on the \end whatsit — Perl semantics).

pub fn after_digest_begin(self, hook: DigestionClosure) -> Self

Push an afterDigestBegin hook (environments: runs on the \begin whatsit right after its arguments digest).

pub fn after_digest_body(self, hook: DigestionClosure) -> Self

Push an afterDigestBody hook (environments / box constructors: runs on the whatsit after the captured body digests — Perl’s afterDigestBody).

pub fn before_digest(self, hook: BeforeDigestClosure) -> Self

Push a beforeDigest hook (runs before the arguments are digested — Perl’s beforeDigest => sub {…}, e.g. \footnote’s neutralize_font).

pub fn before_digest_end(self, hook: BeforeDigestClosure) -> Self

Push a beforeDigestEnd hook (environments: before \end{…} digests).

pub fn before_construct(self, hook: ConstructionClosure) -> Self

Push a beforeConstruct hook (runs before the replacement absorbs).

pub fn after_construct(self, hook: ConstructionClosure) -> Self

Push an afterConstruct hook (runs after the replacement absorbs).

pub fn properties(self, props: PropertiesClosure) -> Self

Set the properties closure (computes the whatsit’s property map from the digested args — Perl’s properties => sub {…} / properties => {…}).

pub fn reversion(self, rev: Reversion) -> Self

Set the reversion (reversion => "…" token form or a closure).

pub fn font(self, font: FontDirective) -> Self

Set the font directive (font => { family => …, … }).

pub fn sizer(self, sizer: SizingClosure) -> Self

Set the sizer (sizer => sub {…} computing (width, height, depth)).

pub fn install(self) -> Result<()>

Install the accumulated definition.
