Function extract_patch_displays 

pub async fn extract_patch_displays(
    resource: &LockedResource,
    cache: &Cache,
) -> Vec<PatchDisplay>

Extract patch display information for a locked resource.

This function:

1. Reads the original file from the source worktree
2. Parses it to extract original field values
3. Combines with the overridden values from the applied patches
4. Returns formatted patch display information

Arguments

• resource - The locked resource with patch information
• cache - Repository cache to access source worktrees

Returns

A vector of PatchDisplay entries with original and overridden values. If the source file cannot be read or parsed, displays show only overridden values with “(none)” for the original value.

Examples

use agpm_cli::lockfile::patch_display::extract_patch_displays;
use agpm_cli::lockfile::LockedResourceBuilder;
use agpm_cli::cache::Cache;
use agpm_cli::core::ResourceType;

let cache = Cache::new()?;
let resource = LockedResourceBuilder::new(
    "test".to_string(),
    "agents/test.md".to_string(),
    "sha256:def456".to_string(),
    "agents/test.md".to_string(),
    ResourceType::Agent,
)

let displays = extract_patch_displays(&resource, &cache).await;
for display in displays {
    println!("{}", display.format());
}
