Struct rerun::MemoryLimit

source · 
pub struct MemoryLimit {
    pub max_bytes: Option<i64>,
}
Expand description

Represents a limit in how much RAM to use for the entire process.

Different systems can chose to heed the memory limit in different ways, e.g. by dropping old data when it is exceeded.

It is recommended that they log using re_log::info_once when they drop data because a memory limit is reached.

Fields§

§max_bytes: Option<i64>

Limit in bytes.

This is primarily compared to what is reported by crate::AccountingAllocator (‘counted’). We limit based on this instead of resident (RSS) because counted is what we have immediate control over, while RSS depends on what our allocator (MiMalloc) decides to do.

Implementations§

source§

impl MemoryLimit

source

pub const UNLIMITED: MemoryLimit = _

No limit.

source

pub fn from_bytes(max_bytes: u64) -> MemoryLimit

Set the limit to some number of bytes.

source

pub fn from_fraction_of_total(fraction: f32) -> MemoryLimit

Set the limit to some fraction (0-1) of the total available RAM.

source

pub fn parse(limit: &str) -> Result<MemoryLimit, String>

The limit can either be absolute (e.g. “16GB”) or relative (e.g. “50%”).

source

pub fn is_limited(&self) -> bool

source

pub fn is_unlimited(&self) -> bool

source

pub fn is_exceeded_by(&self, mem_use: &MemoryUse) -> Option<f32>

Returns how large fraction of memory we should free to go down to the exact limit.
