Struct ResourceLimits 

pub struct ResourceLimits {
    pub data_bytes: u64,
    pub wal_bytes: u64,
    pub tracked_pages: u32,
    pub readers: u32,
    pub record_bytes: u32,
    pub recovery_bytes: u64,
}

Fields

data_bytes: u64

wal_bytes: u64

tracked_pages: u32

Maximum retired pages AND recycled pages tracked in one epoch.

readers: u32

record_bytes: u32

recovery_bytes: u64

Space kept unavailable to normal writes for an operator’s recovery work. Crash restart itself needs no new data pages in this mode.

Implementations

impl ResourceLimits

pub fn validate(self) -> Result<Self>

pub fn freelist_bytes(self) -> u64

pub fn total_bytes(self) -> Result<u64>

Maximum managed logical bytes, including both freelist candidates, fixed reader slots and unused recovery allowance. Filesystem metadata, allocation rounding, unrelated files and recovery exports are separate.

pub fn encode(self) -> Vec<u8>

The 56-byte E4LIMIT1 policy record. Public so a format owner above the kernel (typed collections on the page-WAL) persists the identical bytes instead of a second encoding of the same six fields.

pub fn decode(b: &[u8]) -> Result<Self>
