Struct ExtsortConfig

#[non_exhaustive]
pub struct ExtsortConfig {
    pub temp_file_folder: PathBuf,
    pub compress_with: CompressionCodec,
    /* private fields */
}

The configuration for the external sorting.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

temp_file_folder: PathBuf

compress_with: CompressionCodec

Implementations

impl ExtsortConfig

pub fn new() -> Self

Creates a configuration with a sort buffer size of 10M and a sort directory of /tmp

It is recommended to increase the sort buffer size for improved performance.

pub fn with_buffer_size(sort_buf_bytes: usize) -> Self

Creates a configuration with a specified sort buffer size in bytes and a sort directory of /tmp

pub fn create_with_buffer_size_for<T>(sort_buf_bytes: usize) -> Self

👎Deprecated: Use new() or the Default impl instead. These do not require a type annotation

Creates a configuration with a specified sort buffer size in bytes and a sort directory of /tmp

pub fn default_for<T>() -> Self

👎Deprecated: Use new() or the Default impl instead. These do not require a type annotation

Creates a configuration with a sort buffer size of 10M and a sort directory of /tmp

pub fn temp_file_folder(self, folder: impl Into<PathBuf>) -> Self

Updates the temp_file_folder attribute. Useful for fluent-style api usage.

pub fn compress_lz4_flex(self) -> Self

pub fn sort_buffer_size(self, new_size: usize) -> Self

sets the sort buffer size in bytes

Trait Implementations

impl Default for ExtsortConfig

fn default() -> Self

Returns the “default value” for a type.
