Implementations

impl PType

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of PType.

pub fn from_i32(value: i32) -> Option<PType>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a PType, or None if value is not a valid variant.

impl PType

pub const fn is_unsigned_int(self) -> bool

Returns true iff this PType is an unsigned integer type

pub const fn is_signed_int(self) -> bool

Returns true iff this PType is a signed integer type

pub const fn is_int(self) -> bool

Returns true iff this PType is an integer type Equivalent to self.is_unsigned_int() || self.is_signed_int()

pub const fn is_float(self) -> bool

Returns true iff this PType is a floating point type

pub const fn byte_width(&self) -> usize

Returns the number of bytes in this PType

pub const fn bit_width(&self) -> usize

Returns the number of bits in this PType

pub fn max_value_as_u64(&self) -> u64

Returns the maximum value of this PType if it is an integer type Returns u64::MAX if the value is too large to fit in a u64

pub const fn to_signed(self) -> Self

Returns the PType that corresponds to the signed version of this PType

pub const fn to_unsigned(self) -> Self

Returns the PType that corresponds to the unsigned version of this PType For floating point types, this will simply return self
