Struct PrettyBlock

pub struct PrettyBlock<'a> { /* private fields */ }

Methods from Deref<Target = RawBlock>

pub fn ncols(&self) -> usize

Number of columns

pub fn nrows(&self) -> usize

Number of rows

pub fn precision(&self) -> Precision

Precision for current block.

pub fn group_id(&self) -> u64

pub fn table_name(&self) -> Option<&str>

pub fn tmq_db_name(&self) -> Option<&str>

pub fn schemas(&self) -> &[ColSchema]

pub fn field_names(&self) -> &[String]

Get field names.

pub fn columns(&self) -> Iter<'_, ColumnView>

Data view in columns.

pub fn column_views(&self) -> &[ColumnView]

pub fn rows<'a>(&self) -> RowsIter<'a>

Data view in rows.

pub fn deserialize<'de, 'a: 'de, T>( &'a self, ) -> Map<RowsIter<'_>, fn(RowView<'a>) -> Result<T, Error>>

where T: Deserialize<'de>,

pub fn as_raw_bytes(&self) -> &[u8]

pub fn is_null(&self, row: usize, col: usize) -> bool

pub unsafe fn get_raw_value_unchecked( &self, row: usize, col: usize, ) -> (Ty, u32, *const c_void)

Get one value at (row, col) of the block.

Safety

(row, col) should not exceed the block limit.

pub fn get_ref(&self, row: usize, col: usize) -> Option<BorrowedValue<'_>>

pub unsafe fn get_ref_unchecked( &self, row: usize, col: usize, ) -> BorrowedValue<'_>

Get one value at (row, col) of the block.

Safety

Ensure that row and col not exceed the limit of the block.

pub fn to_values(&self) -> Vec<Vec<Value>>

pub fn write<W: Write>(&self, _wtr: W) -> Result<usize>

pub fn fields(&self) -> Vec<Field>

pub fn pretty_format(&self) -> PrettyBlock<'_>

pub fn to_create(&self) -> Option<MetaCreate>

pub fn concat(&self, rhs: &Self) -> Self

Concatenate two blocks into one by rows.

Panics

If the two blocks have different schemas.

pub fn cast_precision(&self, precision: Precision) -> Self

Cast the block into a new block with new precision.

Trait Implementations
