Struct CustomDataTypeSnapshot 

pub struct CustomDataTypeSnapshot {
    pub tag: String,
    pub wire_size: WireSize,
}

User-defined custom-type metadata carried inside DataTypeSnapshot::Custom. Boxed in the parent enum so the discriminant stays compact (the migration error variants embed two DataTypeSnapshots each, and an inline String + WireSize would bloat crate::error::DbmsError past clippy’s result_large_err threshold).

Fields

tag: String

Stable type identifier (CustomDataType::TYPE_TAG).

wire_size: WireSize

On-disk wire layout used by the snapshot codec.

Trait Implementations

impl Clone for CustomDataTypeSnapshot

fn clone(&self) -> CustomDataTypeSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CustomDataTypeSnapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CustomDataTypeSnapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for CustomDataTypeSnapshot

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 PartialEq for CustomDataTypeSnapshot

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
