Struct LineLength 

pub struct LineLength(/* private fields */);

A line length value that can be 0 (meaning no limit) or a positive value (≥1)

Many configuration values for line length need to support both:

• 0: Special value meaning “no line length limit”
• ≥1: Actual line length limit

This type enforces those constraints at deserialization time.

Implementations

impl LineLength

pub fn new(value: usize) -> Self

Create a new LineLength, where 0 means no limit and values ≥1 are actual limits.

pub fn get(self) -> usize

Get the underlying value (0 for no limit, otherwise the actual limit).

pub fn is_unlimited(self) -> bool

Check if this represents “no limit” (value was 0).

pub fn effective_limit(self) -> usize

Get the effective limit for comparisons. Returns usize::MAX for unlimited, otherwise the actual limit.

pub const fn from_const(value: usize) -> Self

Convert from a default value (for use in config defaults).

Panics

Never panics - accepts any value including 0.

Trait Implementations

impl Clone for LineLength

fn clone(&self) -> LineLength

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineLength

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

Formats the value using the given formatter.

impl Default for LineLength

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LineLength

We don’t need a separate error type since LineLength accepts all values. The validation is implicit in the conversion.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LineLength

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

Formats the value using the given formatter.

impl From<LineLength> for usize

fn from(val: LineLength) -> Self

Converts to this type from the input type.

impl Hash for LineLength

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl JsonSchema for LineLength

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 Ord for LineLength

fn cmp(&self, other: &LineLength) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LineLength

fn eq(&self, other: &LineLength) -> 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 PartialOrd for LineLength

fn partial_cmp(&self, other: &LineLength) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for LineLength

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for LineLength

impl Eq for LineLength
