Struct DsSchema 

pub struct DsSchema {
    pub id: u32,
    pub name: String,
    pub fields: BTreeMap<u32, FieldConstraint>,
}

Schema definition for structured data.

Fields

id: u32

Schema ID.

name: String

Schema name.

fields: BTreeMap<u32, FieldConstraint>

Fields in the schema.

Implementations

impl DsSchema

pub fn new(id: u32, name: &str) -> Self

Create a new DsSchema.

pub fn add_field( &mut self, tag: u32, name: &str, field_type: FieldType, nullable: bool, )

Add a field to the schema.

pub fn validate(&self, value: &DsValue) -> DsResult<()>

Validate a value against the schema.

Trait Implementations

impl Clone for DsSchema

fn clone(&self) -> DsSchema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DsSchema

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DsSchema

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DsSchema

fn eq(&self, other: &DsSchema) -> 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 PartialOrd for DsSchema

fn partial_cmp(&self, other: &DsSchema) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for DsSchema

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
