Struct Precondition 

pub struct Precondition {
    pub param: String,
    pub expression: Option<String>,
    pub description: Option<String>,
    pub type_hint: Option<String>,
    pub source: ConditionSource,
}

A precondition on a function parameter.

Fields

param: String

Parameter name

expression: Option<String>

Constraint expression (e.g., “x > 0”)

description: Option<String>

Human-readable description from docstring

type_hint: Option<String>

Type hint if present

source: ConditionSource

Source of this condition

Trait Implementations

impl Clone for Precondition

fn clone(&self) -> Precondition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Precondition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Precondition

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Precondition

fn eq(&self, other: &Precondition) -> 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 Precondition

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
