Extracted function info from AST.

Fields

name: String

start_line: usize

end_line: usize

name_col: usize

0-based column of the function name identifier.

name_end_col: usize

0-based end column of the function name identifier.

line_count: usize

complexity: usize

Cyclomatic complexity (1 + number of branch points).

body_hash: Option<u64>

Hash of the function body AST structure for duplicate detection.

is_exported: bool

Whether this function is exported (pub/export).

parameter_count: usize

Number of parameters.

external_refs: Vec<String>

Names of external identifiers referenced in the body (for Feature Envy).

chain_depth: usize

Max method chain depth in the body (for Message Chains).

switch_arms: usize

Number of switch/match arms (for Switch Statements).

is_delegating: bool

Whether this function only delegates to another object’s method (for Middle Man).

parameter_types: Vec<TypeRef>

Parameter types in declaration order, each resolved to a TypeRef. Preserves position (first param = index 0) so positional analyses work.

comment_lines: usize

Number of comment lines in the function body.

referenced_fields: Vec<String>

Field names referenced in this function body (for Temporary Field).

null_check_fields: Vec<String>

Field names checked for null/None in this function (for Null Object pattern).

switch_dispatch_target: Option<String>

The field/variable name being dispatched on in switch/match (for Strategy/State).

optional_param_count: usize

Number of optional parameters (for Builder pattern).

called_functions: Vec<String>

Names of functions/methods called in this function body (for call graph).

cognitive_complexity: usize

Cognitive complexity score [SonarSource 2017] — nesting-aware understandability metric.

return_type: Option<TypeRef>

Declared return type (None if not annotated or inferred), resolved the same way as parameter types. Drives return_type_leak detection.

Trait Implementations
