Struct DeltaTableSnapshot 

Source 
pub struct DeltaTableSnapshot { /* private fields */ }
Expand description

Loaded Delta snapshot metadata awaiting logical Arrow schema conversion.

Implementations§

Source§

impl DeltaTableSnapshot

Source

pub fn version(&self) -> u64

Returns the loaded Delta snapshot version.

Source

pub fn protocol(&self) -> &DeltaProtocol

Returns the loaded Delta protocol metadata.

Source

pub fn table_url(&self) -> &str

Returns the normalized table URL.

This value may contain sensitive caller input. Do not log or expose it.

Source

pub fn validate_protocol(&self) -> Result<(), DeltaReaderError>

Validates the loaded snapshot against the supported reader protocol.

Source

pub fn into_table(self) -> Result<DeltaTable, DeltaReaderError>

Converts the logical Arrow schema and finishes constructing the table.
