Macro spmi_register_block 

macro_rules! spmi_register_block {
    (
        pub struct $name:ident {
            $($tail:tt)*
        }
    ) => { ... };
    (@fields) => { ... };
    (@fields $vis:vis $field:ident => $reg_mod:ident, $($tail:tt)*) => { ... };
    (@fields $vis:vis $field:ident => $reg_mod:ident) => { ... };
}

Defines a struct to group multiple SPMI registers.

This macro generates a public struct named $name that holds a device client and provides methods to access individual registers defined by spmi_register!, as well as read_bulk and write_bulk methods for contiguous accesses.

Arguments

1. $name: The identifier for the generated register block struct.
2. { ... }: A block defining the registers contained within this block. The format of each register definition is: $vis $field_name => $reg_mod,
   • $vis: Visibility of the register accessor method (e.g., pub).
   • $field_name: The name of the method generated on the block struct to access the register.
   • $reg_mod: The module identifier of the register defined via spmi_register!.

Examples

spmi_register! {
    my_reg, u8, 0x10, RW, {
        pub enable, set_enable: 7;
    }
}

spmi_register! {
    status_reg, u16, 0x12, RO, LE, {
        pub ready: 0;
    }
}

spmi_register_block! {
    pub struct MyDeviceRegisters {
        pub control => my_reg,
        pub status => status_reg,
    }
}

// Usage:
// let regs = MyDeviceRegisters::new(spmi_device);
// let ctrl_val = regs.control().read().await?;
// let is_ready = regs.status().read().await?.ready();
