Struct GenericMetadata 

pub struct GenericMetadata {
    pub id: String,
    pub payload_size: u64,
    pub original_size: Option<u64>,
    pub ext: Option<Value>,
}

Generic card metadata (JSON-serializable)

Fields

id: String

Payload identifier

payload_size: u64

Payload size in bytes

original_size: Option<u64>

Optional: original size before any transformation

ext: Option<Value>

Format-specific extension data

Implementations

impl GenericMetadata

pub fn new(id: impl Into<String>, payload_size: u64) -> Self

Create minimal metadata

pub fn with_original_size(self, size: u64) -> Self

Builder: set original size

pub fn with_ext(self, ext: Value) -> Self

Builder: set extension data

pub fn to_json(&self) -> Result<Vec<u8>>

Serialize to JSON bytes

pub fn from_json(bytes: &[u8]) -> Result<Self>

Deserialize from JSON bytes

Trait Implementations

impl Clone for GenericMetadata

fn clone(&self) -> GenericMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GenericMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GenericMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for GenericMetadata

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
