Struct Limits 

#[non_exhaustive]
pub struct Limits {
    pub map_lim: usize,
    pub rbuf_mem: usize,
    pub swbuf: usize,
    pub uwbuf: usize,
}

Memory configuration limits.

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.

map_lim: usize

Limit on size of commit write map, default is 5000.

rbuf_mem: usize

Memory for buffering small reads, default is 0x200000.

swbuf: usize

Memory for buffering writes to main storage, default is 0x100000.

uwbuf: usize

Memory for buffering writes to temporary storage, default is 0x100000.

Trait Implementations

impl Default for Limits

fn default() -> Self

Returns the “default value” for a type.
