Method append_block

arrow-array/src/builder/generic_bytes_view_builder.rs:194–201

Append a new data block returning the new block offset Note: this will first flush any in-progress block This allows appending views from blocks added using [`Self::append_block`]. See [`Self::append_value`] for appending individual values ``` # use arrow_array::builder::StringViewBuilder; let mut builder = StringViewBuilder::new(); let block = builder.append_block(b"helloworldbingobongo".into

(&mut self, buffer: Buffer)

    /// assert_eq!(actual, expected);
    /// ```
    pub fn append_block(&mut self, buffer: Buffer) -> u32 {
        assert!(buffer.len() < u32::MAX as usize);

        self.flush_in_progress();
        let offset = self.completed.len();
        self.push_completed(buffer);
        offset as u32
    }

    /// Append a view of the given `block`, `offset` and `length`
    ///
