Struct Expression 

pub struct Expression {
    pub type: Option<i32>,
    pub symbol: Option<String>,
    pub immediate: Option<u64>,
    pub parent_index: Option<i32>,
    pub is_relocation: Option<bool>,
}

An operand consists of 1 or more expressions, linked together as a tree.

Fields

type: Option<i32>

IMMEDIATE_INT is by far the most common type and thus we can save some space by omitting it as the default.

symbol: Option<String>

Symbol for this expression. Interpretation depends on type. Examples include: “eax”, “[”, “+”

immediate: Option<u64>

If the expression can be interpreted as an integer value (IMMEDIATE_INT) the value is given here.

parent_index: Option<i32>

The parent expression. Example expression tree for the second operand of: mov eax, b4 [ebx + 12] “b4” — “[” — “+” — “ebx” \ “12”

is_relocation: Option<bool>

true if the expression has entry in relocation table

Implementations

impl Expression

pub fn type(&self) -> Type

Returns the enum value of type, or the default if the field is unset or set to an invalid enum value.

pub fn set_type(&mut self, value: Type)

Sets type to the provided enum value.

pub fn symbol(&self) -> &str

Returns the value of symbol, or the default value if symbol is unset.

pub fn immediate(&self) -> u64

Returns the value of immediate, or the default value if immediate is unset.

pub fn parent_index(&self) -> i32

Returns the value of parent_index, or the default value if parent_index is unset.

pub fn is_relocation(&self) -> bool

Returns the value of is_relocation, or the default value if is_relocation is unset.

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl Default for Expression

fn default() -> Self

Returns the “default value” for a type.

impl Message for Expression

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Expression

fn eq(&self, other: &Expression) -> 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.
