Struct RelationContext

struct RelationContext<'a> {
    pair: Pair<'a, Rule>,
    line_no: i64,
    children: Vec<Box<Rel>>,
    input_field_count: usize,
    advanced_extension: Option<AdvancedExtension>,
}

Expand description

Intermediate state for relation parsing: the structural tree data (children, addenda) has been processed into proto types, but the relation’s own grammar pair hasn’t been parsed yet.

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T, U> Into<U> for T
where U: From<T>,

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

impl<T, U> TryFrom<U> for T
where U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.
