Struct ParamInsertionInfo 

pub struct ParamInsertionInfo {
    pub line: usize,
    pub char_pos: usize,
    pub needs_comma: bool,
    pub multiline_indent: Option<String>,
}

Information about where to insert a new parameter in a function signature.

Fields

line: usize

Line number (1-indexed) where the new parameter should be inserted.

char_pos: usize

Character position where the new parameter should be inserted.

needs_comma: bool

Whether a comma needs to be added before the new parameter.

For single-line signatures: prepend , to the new parameter text. For multiline signatures (multiline_indent is Some): if true, the last argument has no trailing comma and one must be appended there; if false, a trailing comma already exists and only the new-line + indent prefix is needed.

multiline_indent: Option<String>

For multiline signatures where ) sits on its own line: the indentation string (spaces/tabs) to use for the new parameter. The insertion point (line / char_pos) is set to right after the last argument’s content rather than at the ) itself.

When Some, callers should produce:

• needs_comma=true → insert ,\n<indent><param> (adds trailing comma to prev arg)
• needs_comma=false → insert \n<indent><param>, (mirrors trailing-comma style)

When None this is a single-line (or inline-paren) signature and the classic , <param> / <param> text applies.

Trait Implementations

impl Clone for ParamInsertionInfo

fn clone(&self) -> ParamInsertionInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamInsertionInfo

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

Formats the value using the given formatter.

impl PartialEq for ParamInsertionInfo

fn eq(&self, other: &ParamInsertionInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
