Struct CustomShaderRenderer 

pub struct CustomShaderRenderer { /* private fields */ }

Custom shader renderer that applies post-processing effects

Implementations

impl CustomShaderRenderer

pub fn new( device: &Device, _queue: &Queue, surface_format: TextureFormat, shader_path: &Path, width: u32, height: u32, animation_enabled: bool, animation_speed: f32, window_opacity: f32, text_opacity: f32, full_content_mode: bool, ) -> Result<Self>

Create a new custom shader renderer from a GLSL shader file

Arguments

• device - The wgpu device
• queue - The wgpu queue
• surface_format - The surface texture format
• shader_path - Path to the GLSL shader file
• width - Initial viewport width
• height - Initial viewport height
• animation_enabled - Whether to animate iTime
• animation_speed - Animation speed multiplier

pub fn intermediate_texture_view(&self) -> &TextureView

Get a view of the intermediate texture for rendering terminal content into

pub fn resize(&mut self, device: &Device, width: u32, height: u32)

Resize the intermediate texture when window size changes

pub fn render( &mut self, device: &Device, queue: &Queue, output_view: &TextureView, ) -> Result<()>

Render the custom shader effect to the output texture

This should be called after the terminal content has been rendered to the intermediate texture obtained via intermediate_texture_view().

pub fn animation_enabled(&self) -> bool

Check if animation is enabled

pub fn set_animation_enabled(&mut self, enabled: bool)

Set animation enabled state

pub fn set_animation_speed(&mut self, speed: f32)

Update animation speed multiplier

pub fn set_opacity(&mut self, opacity: f32)

Update window opacity (content alpha passed to shader)

pub fn set_full_content_mode(&mut self, enabled: bool)

Update full content mode

pub fn full_content_mode(&self) -> bool

Check if full content mode is enabled

pub fn set_mouse_position(&mut self, x: f32, y: f32)

Update mouse position in pixel coordinates

Arguments

• x - Mouse X position in pixels (0 = left edge)
• y - Mouse Y position in pixels (0 = top edge, will be flipped for shader)

pub fn set_mouse_button(&mut self, pressed: bool, x: f32, y: f32)

Update mouse button state and click position

Call this when the left mouse button is pressed or released.

Arguments

• pressed - True if mouse button is now pressed, false if released
• x - Mouse X position in pixels at time of click/release
• y - Mouse Y position in pixels at time of click/release (will be flipped for shader)

pub fn reload_from_source( &mut self, device: &Device, source: &str, name: &str, ) -> Result<()>

Reload the shader from a source string

This method compiles the new shader source and replaces the current pipeline. If compilation fails, returns an error and the old shader remains active.

Arguments

• device - The wgpu device
• source - The GLSL shader source code
• name - A name for error messages (e.g., “editor”)

Returns

Ok(()) if successful, Err with error message if compilation fails
