Detailed parameter usage pattern

Fields

is_read: bool

Parameter is read without modification

is_mutated: bool

Parameter is modified (assigned to)

is_moved: bool

Parameter is moved/consumed (passed to function that takes ownership)

escapes_through_return: bool

Parameter escapes through return

is_stored: bool

Parameter is stored in a struct/container

used_in_closure: bool

Parameter is used in a closure

used_in_loop: bool

Parameter is used in loops (affects borrowing strategy)

field_accesses: HashSet<String>

Nested field access patterns

method_calls: HashSet<String>

Method calls on the parameter

usage_sites: Vec<UsageSite>

Specific expressions where parameter is used

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for ParameterUsagePattern

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