On-disk storage configuration.

Fields

path: PathBuf

The path to the folder where any files created or read by the storage component will exist.

If the folder doesn’t exist, it and any required parents will be created.

max_block_store_size: usize

The maximum size of the database to use for the block store.

The size should be a multiple of the OS page size.

max_deploy_store_size: usize

The maximum size of the database to use for the deploy store.

The size should be a multiple of the OS page size.

max_deploy_metadata_store_size: usize

The maximum size of the database to use for the deploy metadata store.

The size should be a multiple of the OS page size.

max_state_store_size: usize

The maximum size of the database to use for the component state store.

The size should be a multiple of the OS page size.

enable_mem_deduplication: bool

Whether or not memory deduplication is enabled.

mem_pool_prune_interval: u16

How many loads before memory duplication checks for dead references.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DataSize for Config

const IS_DYNAMIC: bool = true

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

fn estimate_detailed_heap_size(&self) -> MemUsageNode

Create a tree of memory estimations.

impl Debug for Config

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

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Config

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Config

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
