Implementations

impl Expression

pub fn location(&self) -> &SourceLocation

pub fn to_source_string<'a>(&self, source: &'a [u8]) -> Option<&'a str>

Convert this expression back to source text

pub fn walk<'s, F>(&'s self, f: &mut F)

where F: FnMut(&'s Self),

Recursively walk all nested expressions. The closure receives a &'s Expression tied to self’s lifetime, so references extracted inside the closure can be stored in an outer Vec<&'s T>.

pub fn extract_variable_name<'a>(&self, source: &'a [u8]) -> Option<&'a str>

Extract variable name from simple expressions (Identifier or FieldAccess)

pub fn is_null(&self) -> bool

Check if this expression is NULL Handles both Expression::Null and the identifier “NULL” (common in C code)

pub fn is_zero(&self) -> bool

Check if this expression is the number 0

pub fn is_string_literal(&self) -> bool

Check if this expression is a string literal

pub fn extract_string_value(&self) -> Option<String>

Extract string literal value, unwrapping macro calls like I_(“string”) Returns the string without quotes

pub fn is_string_or_macro_string(&self) -> bool

Check if this is a string literal or a macro wrapping a string literal

pub fn contains_identifier(&self, name: &str) -> bool

Check if this expression contains an identifier with the given name Recursively searches through the entire expression tree

pub fn collect_identifiers(&self) -> Vec<String>

Collect all identifiers in this expression Returns a list of all identifier names found in the expression tree

pub fn is_call_to(&self, function_name: &str) -> bool

Check if this expression is a call to the specified function

pub fn is_call_to_any(&self, function_names: &[&str]) -> bool

Check if this expression is a call to any of the specified functions

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl Serialize for Expression

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
