Struct Frame 

pub struct Frame {
    pub schema: Value,
    pub partition_by: Vec<String>,
    pub created_at: DateTime<Utc>,
    pub max_partitions: u32,
    pub properties: HashMap<String, String>,
}

A Frame represents a table within a box.

Fields

schema: Value

Schema of the frame (Arrow schema JSON).

partition_by: Vec<String>

Columns to partition by.

created_at: DateTime<Utc>

When this frame was created.

max_partitions: u32

Maximum number of partitions allowed (default: 10,000).

properties: HashMap<String, String>

Custom properties for this frame.

Implementations

impl Frame

pub fn new(schema: Value) -> Self

Create a new frame with a schema.

pub fn with_partitioning(schema: Value, partition_by: Vec<String>) -> Self

Create a new frame with schema and partitioning.

Trait Implementations

impl Clone for Frame

fn clone(&self) -> Frame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Frame

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Frame

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Frame

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
