pub struct QuantizedVector {
pub data: Vec<u8>,
pub min: f32,
pub max: f32,
}Expand description
A quantized vector using 8-bit scalar quantization.
Each f32 value is mapped to a u8 (0-255) using min/max scaling.
The original value can be reconstructed as: value = (data[i] / 255.0) * (max - min) + min
Fields§
§data: Vec<u8>Quantized data (1 byte per dimension instead of 4).
min: f32Minimum value in the original vector.
max: f32Maximum value in the original vector.
Implementations§
Source§impl QuantizedVector
impl QuantizedVector
Sourcepub fn to_f32(&self) -> Vec<f32>
pub fn to_f32(&self) -> Vec<f32>
Reconstructs the original f32 vector from quantized data.
Note: This is a lossy operation. The reconstructed values are approximations.
Sourcepub fn memory_size(&self) -> usize
pub fn memory_size(&self) -> usize
Returns the memory size in bytes.
Sourcepub fn from_bytes(bytes: &[u8]) -> Result<Self>
pub fn from_bytes(bytes: &[u8]) -> Result<Self>

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().

painted.white();Source§fn bright_black(&self) -> Painted<&T>

fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
