Struct ToolInvocation 

#[repr(C)]
pub struct ToolInvocation {
    pub tool_id: u32,
    pub arg_layout: u64,
    pub args_offset: u32,
    pub args_len: u32,
}

Zero-copy tool invocation

Fields

tool_id: u32

Pre-resolved tool ID (compile-time lookup)

arg_layout: u64

Bitfield describing argument positions and types

args_offset: u32

Offset into shared memory for arguments

args_len: u32

Length of arguments in shared memory

Implementations

impl ToolInvocation

pub const SIZE: usize = 24

Size of the struct in bytes

pub const MAX_ARGS: usize = 16

Maximum number of arguments that can be encoded in arg_layout Each argument uses 4 bits for type, so 64 bits / 4 = 16 args

pub fn new( tool_id: u32, arg_layout: u64, args_offset: u32, args_len: u32, ) -> Self

Create a new tool invocation

pub fn from_bytes(bytes: impl AsRef<[u8]>) -> Result<Self, DCPError>

Parse from bytes.

pub fn as_bytes(&self) -> [u8; 24]

Serialize to canonical bytes with reserved padding zeroed.

pub fn get_arg_type(&self, index: usize) -> Option<ArgType>

Get the type of argument at the given index (0-15)

pub fn set_arg_type(&mut self, index: usize, arg_type: ArgType)

Set the type of argument at the given index (0-15)

pub fn arg_count(&self) -> usize

Count the number of non-null arguments

Trait Implementations

impl Clone for ToolInvocation

fn clone(&self) -> ToolInvocation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ToolInvocation

impl Debug for ToolInvocation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ToolInvocation

impl PartialEq for ToolInvocation

fn eq(&self, other: &ToolInvocation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
