Struct ConfigValueGroup 

pub struct ConfigValueGroup {
    pub compression_scheme_retest_interval: usize,
    pub compression_policy: ConfigEnum,
    pub simulation_max_bytes: Option<ByteSize>,
    pub simulation_max_chunks: Option<usize>,
}

ConfigValueGroup struct containing all configurable values

Fields

compression_scheme_retest_interval: usize

How often should we retest the compression scheme? Determining the optimal compression scheme takes time, but it also minimizes the storage costs of the data.

If set to zero, it’s set once per file block per xorb.

The default value is 32.

Use the environment variable HF_XET_XORB_COMPRESSION_SCHEME_RETEST_INTERVAL to set this value.

compression_policy: ConfigEnum

Compression policy for xorb data. Valid values: “” or “auto” for automatic detection, “none”, “lz4”, “bg4-lz4”. When set to “” or “auto”, the best compression scheme is chosen based on data analysis.

The default value is “auto” (auto-detect).

Use the environment variable HF_XET_XORB_COMPRESSION_POLICY to set this value.

simulation_max_bytes: Option<ByteSize>

Override the maximum xorb size in bytes for simulation mode. When set to Some(value), this overrides the hard-coded MAX_XORB_BYTES cutting threshold in simulation builds. When None (default), the standard constant is used.

Only effective when the simulation feature is enabled.

Use the environment variable HF_XET_XORB_SIMULATION_MAX_BYTES to set this value.

simulation_max_chunks: Option<usize>

Override the maximum xorb chunk count for simulation mode. When set to Some(value), this overrides the hard-coded MAX_XORB_CHUNKS cutting threshold in simulation builds. When None (default), the standard constant is used.

Only effective when the simulation feature is enabled.

Use the environment variable HF_XET_XORB_SIMULATION_MAX_CHUNKS to set this value.

Implementations

impl ConfigValueGroup

pub fn new() -> Self

Create a new instance with default values only (no environment variable overrides).

pub fn apply_env_overrides(&mut self)

Apply environment variable overrides to this configuration group.

The group name is derived from the module path. For example, in module xet_config::groups::data, the env var for TEST_INT would be HF_XET_DATA_TEST_INT.

pub fn field_names() -> &'static [&'static str]

Returns the list of field names in this configuration group.

pub fn get(&self, name: &str) -> Result<String, ConfigError>

Get a configuration field’s string representation by name.

Trait Implementations

impl AsRef<ConfigValueGroup> for ConfigValueGroup

fn as_ref(&self) -> &ConfigValueGroup

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ConfigValueGroup

fn clone(&self) -> ConfigValueGroup

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConfigValueGroup

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ConfigValueGroup

fn default() -> Self

Returns the “default value” for a type.
