Trait SpmiDevice 

pub trait SpmiDevice {
    // Required methods
    async fn read_reg(&self, address: u16, size: u32) -> Result<Vec<u8>, Error>;
    async fn write_reg(&self, address: u16, data: &[u8]) -> Result<(), Error>;
}

Trait for SPMI devices to abstract register read/write operations.

This trait allows the Register and spmi_register_block! macros to interact with any underlying hardware interface or mock device that implements these basic SPMI read and write operations.

Implementations must handle the low-level transport (e.g., FIDL calls to a Fuchsia SPMI driver) and handle error mapping.

Required Methods

async fn read_reg(&self, address: u16, size: u32) -> Result<Vec<u8>, Error>

Reads a contiguous sequence of bytes from the device.

Arguments

• address - The 16-bit base register address to read from.
• size - The number of bytes to read.

Returns

Returns a vector containing the read bytes on success, or a crate::Error on failure.

async fn write_reg(&self, address: u16, data: &[u8]) -> Result<(), Error>

Writes a contiguous sequence of bytes to the device.

Arguments

• address - The 16-bit base register address to write to.
• data - The byte slice to write to the device.

Returns

Returns Ok(()) on success, or a crate::Error on failure.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
