Implementations§

Source§

impl IcebergSourceConfig

Source

pub fn from_config(config: &ConnectorConfig) -> Result<Self, ConnectorError>

Parses source settings from resolved connector configuration.

snapshot mode without an explicit ID selects the current snapshot at open and remains pinned to it. append mode uses that same selection as its lineage root.

§Errors

Returns an error for missing, malformed, or contradictory settings.

Source

pub fn validate_read_limits(&self) -> Result<(), ConnectorError>

Validates programmatically constructed source bounds before external I/O.

§Errors

Returns a configuration error when a resource or timeout bound is zero.
