pub struct VersionLog {
pub current_seq: u64,
pub history: HashMap<String, Vec<VersionEntry>>,
}Expand description
Append-only log keyed by path. Both forward query patterns — “everything since X” and “the latest entry for this path” — are served from the same map.
Fields§
§current_seq: u64Latest assigned sequence number. Monotonically increases.
history: HashMap<String, Vec<VersionEntry>>Per-path history, newest-last; capped at HISTORY_LIMIT entries.
Implementations§
Source§impl VersionLog
impl VersionLog
Sourcepub fn record(
&mut self,
path: impl Into<String>,
agent_id: u64,
op: EditOp,
hash: u64,
size: u64,
timestamp_ms: i64,
) -> u64
pub fn record( &mut self, path: impl Into<String>, agent_id: u64, op: EditOp, hash: u64, size: u64, timestamp_ms: i64, ) -> u64
Record one edit. Returns the assigned seq, which is what the host builtin echoes back to the caller.
Sourcepub fn changes_since(
&self,
since: u64,
limit: Option<usize>,
) -> Vec<ChangeRecord>
pub fn changes_since( &self, since: u64, limit: Option<usize>, ) -> Vec<ChangeRecord>
Every change record with seq > since, ordered by seq ascending.
limit (when present) keeps the most recent limit entries.
Sourcepub fn last_entry(&self, path: &str) -> Option<&VersionEntry>
pub fn last_entry(&self, path: &str) -> Option<&VersionEntry>
Latest entry recorded for path, or None if untracked.

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().

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.

renamed to 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);
