Struct SchemaField 

pub struct SchemaField {
    pub name: String,
    pub constraint: TypeConstraint,
    pub offset: u32,
    pub size: u32,
    pub align: u8,
}

A field within a schema

Fields

name: String

Field name

constraint: TypeConstraint

Field type constraint (includes base type and optional constraints like MaxBytes)

offset: u32

Byte offset within the encoded row

size: u32

Size in bytes

align: u8

Alignment requirement

Implementations

impl SchemaField

pub fn new(name: impl Into<String>, constraint: TypeConstraint) -> Self

Create a new schema field with a type constraint. Offset, size, and alignment are computed when added to a Schema.

pub fn unconstrained(name: impl Into<String>, field_type: Type) -> Self

Create a new schema field with an unconstrained type. Convenience method for the common case of no constraints.

Trait Implementations

impl Clone for SchemaField

fn clone(&self) -> SchemaField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaField

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SchemaField

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SchemaField

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for SchemaField
