Struct Field

pub struct Field<'s> {
    pub name: &'s str,
    pub shape: ShapeDesc,
    pub offset: Option<NonMaxU32>,
}

Fields

name: &'s str

key for the map field

shape: ShapeDesc

schema of the inner type

offset: Option<NonMaxU32>

offset of the field in the map, if known.

For example, when deserializing a self-descriptive format like JSON, we’re going to get some map fields with dynamically discovered field names, and they’re not going to have an offset.

However, when deserializing formats that are non-self descriptive and working from an existing shape, then their map fields are probably going to have offsets, especially if they’re using derived macros.

Trait Implementations

impl<'s> Clone for Field<'s>

fn clone(&self) -> Field<'s>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'s> Debug for Field<'s>

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

Formats the value using the given formatter.

impl<'s> Hash for Field<'s>

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<'s> PartialEq for Field<'s>

fn eq(&self, other: &Field<'s>) -> 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.
