Struct Config 

#[non_exhaustive]
pub struct Config {
    pub data_transfer_timeout: u32,
    pub use_cmd23: bool,
    pub use_acmd23: bool,
}

SDMMC configuration

Default values: data_transfer_timeout: 5_000_000 use_cmd23: false use_acmd23: false

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.

data_transfer_timeout: u32

The timeout to be set for data transfers, in card bus clock periods

use_cmd23: bool

Pre-declare block count via CMD23 before CMD25, skipping CMD12. Honored only if the card advertises support; falls back silently otherwise (see [StorageDevice::supports_cmd23]).

use_acmd23: bool

Send ACMD23 (SET_WR_BLK_ERASE_COUNT) before CMD25 as a pre-erase hint. Mandatory in SD spec v2+, so honored unconditionally.

Trait Implementations

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.
