Struct SnapshotEntityPage 

pub struct SnapshotEntityPage {
    pub page_number: usize,
    pub total_pages: usize,
    pub entities: Vec<SnapshotEntity>,
    pub is_last: bool,
}

A page of snapshot entities for paginated transfer.

Fields

page_number: usize

Page number (0-indexed).

total_pages: usize

Total number of pages (may be estimated).

entities: Vec<SnapshotEntity>

Entities in this page.

is_last: bool

Whether this is the last page.

Implementations

impl SnapshotEntityPage

pub fn new( page_number: usize, total_pages: usize, entities: Vec<SnapshotEntity>, is_last: bool, ) -> Self

Create a new snapshot page.

pub fn entity_count(&self) -> usize

Number of entities in this page.

pub fn is_empty(&self) -> bool

Check if this page is empty.

pub fn is_valid(&self) -> bool

Check if page is within valid bounds.

Call this after deserializing from untrusted sources.

Trait Implementations

impl BorshDeserialize for SnapshotEntityPage

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for SnapshotEntityPage

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for SnapshotEntityPage

fn clone(&self) -> SnapshotEntityPage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotEntityPage

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

Formats the value using the given formatter.

impl PartialEq for SnapshotEntityPage

fn eq(&self, other: &SnapshotEntityPage) -> 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.
