Struct Config 

pub struct Config {
    pub block_size: u32,
    pub block_count: u32,
    pub read_size: u32,
    pub prog_size: u32,
    pub block_cycles: i32,
    pub cache_size: u32,
    pub lookahead_size: u32,
    pub name_max: u32,
    pub file_max: u32,
    pub attr_max: u32,
}

Filesystem configuration.

Only block_size and block_count are required; the rest have sensible defaults. Create with Config::new and override fields as needed.

Fields

block_size: u32

Size of an erasable block in bytes.

block_count: u32

Number of erasable blocks on the device.

read_size: u32

Minimum read size in bytes. Defaults to 16.

prog_size: u32

Minimum program (write) size in bytes. Defaults to 16.

block_cycles: i32

Number of erase cycles before moving data to a new block. Set to -1 to disable wear leveling.

cache_size: u32

Size of per-file caches in bytes. 0 (default) uses block_size.

lookahead_size: u32

Size of the block allocator lookahead buffer in bytes. 0 (default) uses block_size. Must be a multiple of 8.

name_max: u32

Maximum file name length in bytes. Defaults to 255.

file_max: u32

Maximum file size in bytes.

attr_max: u32

Maximum size of custom attributes in bytes.

Implementations

impl Config

pub fn new(block_size: u32, block_count: u32) -> Self

Create a configuration with the given block geometry and sensible defaults for everything else.
