Struct RowKeyRange 

pub struct RowKeyRange { /* private fields */ }

A canonical primary-row-key half-open interval for one table.

Implementations

impl RowKeyRange

pub const fn full_table(table_id: u32) -> Self

Creates a whole-table range.

pub fn new( table_id: u32, lower_inclusive: Option<u64>, upper_exclusive: Option<u64>, ) -> Result<Self, RowKeyRangeError>

Creates a validated half-open row-id interval within one table.

pub fn from_keys( lower_inclusive: Option<CanonicalRowKey>, upper_exclusive: Option<CanonicalRowKey>, table_id: u32, ) -> Result<Self, RowKeyRangeError>

Creates a range from canonical key bounds, rejecting cross-table input.

pub const fn table_id(self) -> u32

Returns the table covered by this primary-key range.

pub const fn lower_inclusive(self) -> Option<u64>

Returns the lower row-id bound, if it narrows the table minimum.

pub const fn upper_exclusive(self) -> Option<u64>

Returns the upper row-id bound, if it narrows the table end.

pub fn encoded_bounds(self) -> EncodedRowKeyRange

Converts the logical interval into storage scan bytes.

pub fn contains(self, key: CanonicalRowKey) -> bool

Tests a decoded primary row key against the logical half-open interval.
