Struct juniper::parser::Spanning

pub struct Spanning<T> {
    pub item: T,
    pub start: SourcePosition,
    pub end: SourcePosition,
}

Data structure used to wrap items with start and end markers in the input source

A "span" is a range of characters in the input source, starting at the character pointed by the start field and ending just before the end marker.

Fields

item: T

The wrapped item

start: SourcePosition

Start position of the item

end: SourcePosition

End position of the item

This points to the first source position after the wrapped item.
