Enum DangleAlign 

#[non_exhaustive]
pub enum DangleAlign {
    Prefix,
    Open,
    Close,
}

How to align the dangling closing paren.

Only takes effect when Config::dangle_parens is true. Controls where ) is placed when a call wraps onto multiple lines.

At the top level (block depth = 0) Prefix and Close both place the ) at column 0 because the command sits there — the two variants are visually identical in this case:

# Prefix / Close at top level — `)` at column 0:
target_link_libraries(
  mylib PUBLIC dep1
)

# Open — `)` at the opening-paren column:
target_link_libraries(
  mylib PUBLIC dep1
                     )

Inside a nested block (if/foreach/while/function/...) the variants diverge: Prefix tracks the command-name indent (one tab stop per nesting level), while Close places the ) at the current indent level — one tab stop shallower than the command name, i.e. flush with the enclosing block.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Prefix

Align with the start of the command name.

Open

Align with the opening paren column.

Close

No extra indent (flush with current indent level).

Trait Implementations

impl Clone for DangleAlign

fn clone(&self) -> DangleAlign

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DangleAlign

impl Debug for DangleAlign

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

Formats the value using the given formatter.

impl Default for DangleAlign

fn default() -> DangleAlign

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DangleAlign

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for DangleAlign

impl JsonSchema for DangleAlign

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for DangleAlign

fn eq(&self, other: &DangleAlign) -> 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.

impl Serialize for DangleAlign

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
