}

This struct holds the current state of the app. In particular, it has the items field which is a wrapper around ListState. Keeping track of the items state let us render the associated widget with its state and have access to features such as natural scrolling.

Fields

log_analyzer: Box<Arc<dyn LogAnalyzer>>

Api to the backend processor

color: Color

Primary color

selected_module: Module

Currently selected module. Used to manage inputs and highlight focus

show_source_popup: bool

Display the new source popup

show_filter_popup: bool

Display the new filter popup

show_error_message: bool

Display an error message

show_navigation_popup: bool

Display the navigation popup

show_log_options_popup: bool

Display the navigation popup

input_buffers: Vec<Input>

Vector of user input. Entries are uniquely assigned to each UI input, and the selection is performed with the input_buffer_index

input_buffer_index: usize

Currently selected input buffer

formats: StatefulList<String>

Stateful list of all the current formats to be displayed in the source popup

source_type: usize

Tab selector index for Source Type

filter_type: usize

Tab selector index for Filter Type

filter_color: usize

Tab selector index for Filter Type

sources: StatefulTable<(bool, String, Option<String>)>

filters: StatefulTable<(bool, String)>

log_lines: LazyStatefulTable<LogLine>

Lazy widget for the main view of the logs

search_lines: LazyStatefulTable<LogLineStyled>

Lazy widget for the main view of the search

horizontal_offset: usize

Apply an offset to the logs to simulate horizontal scrolling

side_main_size_percentage: u16

Resizing of the side_menu to the main view

log_filter_size_percentage: u16

Resizing on the side_menu between sources and filters

log_search_size_percentage: u16

Resizing on the main view between logs and searchs

log_columns: Vec<(String, bool)>

Active log columns to display in the log and the search

auto_scroll: bool

Auto scroll to the last receive elements. Used for live logs

popup: PopupInteraction

Manage the popup interaction

processing: Processing

Manage the processing popup
