Implementations

impl ArgWrap

pub fn is_some(&self) -> bool

pub fn is_none(&self) -> bool

pub fn is_tokens(&self) -> bool

pub fn eq_text(&self, target: &str) -> bool

Zero-alloc equivalent of self.to_string() == target for keyword checks in DefMacro bodies. Forwards to Token::with_str / Tokens::eq_text for the Token/Tokens variants (covering ~all keyword-argument checks in practice); for other variants falls back to to_string() == target since the Display impl allocates anyway. See Tokens::eq_text for the walk semantics.

pub fn starts_with_text(&self, prefix: &str) -> bool

Zero-alloc self.to_string().starts_with(prefix) for Tokens/Token variants; falls back to full to_string for others.

pub fn mut_tokens(&mut self) -> Option<&mut Tokens>

pub fn owned_tokens(self) -> Option<Tokens>

pub fn try_to_token(self) -> Result<Token>

pub fn expected_token(self) -> Token

pub fn undigested(self) -> Option<Digested>

pub fn to_attribute(&self) -> String

Convert to an attribute string value (for constructor templates) Uses attribute_format for dimensions (1 decimal place) matching Perl

pub fn as_tokens(&self) -> Result<Option<Cow<'_, Tokens>>>

pub fn value_of(&self) -> i64

pub fn value_f64(&self) -> f64

pub fn try_to_number(self) -> Result<Number>

pub fn expect_number(self) -> Number

pub fn try_to_dimension(self) -> Result<Dimension>

pub fn expect_dimension(self) -> Dimension

pub fn try_to_mu_dimension(self) -> Result<MuDimension>

pub fn expect_mu_dimension(self) -> MuDimension

pub fn try_to_glue(self) -> Result<Glue>

pub fn expect_glue(self) -> Glue

pub fn try_to_mu_glue(self) -> Result<MuGlue>

pub fn expect_mu_glue(self) -> MuGlue

pub fn to_mu_dimension(self) -> MuDimension

pub fn to_glue(self) -> Glue

pub fn to_mu_glue(self) -> MuGlue

pub fn expected_keyvals(self) -> KeyVals

pub fn try_to_keyvals(self) -> Result<KeyVals>

pub fn try_to_float(self) -> Result<Float>

pub fn expect_float(self) -> Float

pub fn unlist(self) -> Vec<Token>

pub fn unlist_cow(&self) -> Cow<'_, [Token]>

Borrow the token slice backing an ArgWrap::Tokens, falling back to an owned Vec<Token> for the other variants. Avoids a full Tokens clone in the common ArgWrap::Tokens(_) case.

pub fn is_empty(&self) -> bool
