Struct Formatter 

pub struct Formatter {
    pub format: OutputFormat,
    pub quiet: bool,
    pub vetted: Vec<String>,
    pub compromised: Vec<String>,
    pub show_security_feedback: bool,
}

The Formatter is responsible for generating human-readable and machine-readable output.

It handles:

• Line-by-line diffs (using similar).
• Inline (word-level) diffs for more surgical feedback.
• JSON and Markdown summary reports.

Fields

format: OutputFormat

The desired output format (Text, JSON, Markdown).

quiet: bool

If true, suppresses most console output.

vetted: Vec<String>

Vetted dependency hashes or references.

compromised: Vec<String>

Compromised dependency hashes or references.

show_security_feedback: bool

Show visual security feedback.

Implementations

impl Formatter

pub fn new( format: OutputFormat, quiet: bool, vetted: Vec<String>, compromised: Vec<String>, show_security_feedback: bool, ) -> Self

Creates a new Formatter.

pub fn check_hash_security( &self, action: &str, hash: &str, ) -> HashSecurityStatus

Helper to check security status of a hash.

pub fn format_diff( &self, old: &str, new: &str, results: &[UpdateResult], ) -> String

Generates a standard line-based diff between two strings.

pub fn format_inline_diff( &self, old: &str, new: &str, status: HashSecurityStatus, ) -> String

Generates a word-level inline diff for a single change.

This is particularly useful for showing exactly which part of a URI or hash changed.

pub fn print_results(&self, results: &[UpdateResult])

Prints a summary of all updates in the configured format.
