Implementations

impl DataDescriptor

pub fn validate(&self) -> DataResult<()>

Validate the descriptor, including type/default compatibility.

use daedalus_data::descriptor::{DataDescriptor, DescriptorId, DescriptorVersion};
let desc = DataDescriptor {
    id: DescriptorId::new("example"),
    version: DescriptorVersion::new("1.0"),
    label: None,
    settable: false,
    default: None,
    schema: None,
    codecs: vec![],
    converters: vec![],
    feature_flags: vec![],
    gpu: None,
    type_expr: None,
};
desc.validate().unwrap();

pub fn normalize(self) -> Self

Deterministic ordering for codecs/converters/feature flags.

use daedalus_data::descriptor::{DataDescriptor, DescriptorId, DescriptorVersion};
let desc = DataDescriptor {
    id: DescriptorId::new("id"),
    version: DescriptorVersion::new("1.0"),
    label: None,
    settable: false,
    default: None,
    schema: None,
    codecs: vec!["b".into(), "a".into()],
    converters: vec!["y".into(), "x".into()],
    feature_flags: vec!["b".into(), "a".into()],
    gpu: None,
    type_expr: None,
};
let sorted = desc.normalize();
assert_eq!(sorted.codecs, vec!["a", "b"]);

Trait Implementations

impl Clone for DataDescriptor

fn clone(&self) -> DataDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataDescriptor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DataDescriptor

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DataDescriptor

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
