Struct Field 

pub struct Field {
    pub path: Vec<u32>,
    pub existence_only: bool,
}

A proto field path from the root message, represented as a sequence of field numbers.

For example, Field::new(vec![1, 2, 3]) selects field 3 within the submessage at field 2 within the submessage at field 1.

Field::new(vec![1]) selects field 1 directly.

Fields

path: Vec<u32>

Field numbers from root to this field.

existence_only: bool

If true, the field’s tag is preserved in the output but its value is zeroed (existence-only mode).

Implementations

impl Field

pub fn new(path: Vec<u32>) -> Self

Create a new field path with the given sequence of field numbers.

pub fn existence_only(self) -> Self

Mark this field as existence-only: the field tag is preserved in the output record but the value is set to zero.
