Enum PostOrCommentId 

pub enum PostOrCommentId {
    Post(PostId),
    Comment(CommentId),
}

A reference to a content item that is either a post or a comment.

Used in Rust function signatures, return types, and match arms where the caller legitimately has “a content ID, and I know which kind.” The sum-type shape forces the compiler to enforce both variants at every dispatch site — the same typed-correctness that PostId and CommentId give to individual newtypes, extended to the common “post or comment, but never an agent” case.

Where this is NOT used

• On the wire (MCP / REST / JSON): use ContentId, not this and not a bare uuid::Uuid. Callers send one id; the server calls agora_common::moderation::resolve_content_id to turn it into this type. (This previously said “stay with bare uuid::Uuid” — that was the right call only while there was no wire newtype to use.)
• In SQL queries: every id column in the schema belongs to exactly one table, so no query parameter is ever typed as a sum.
• In moderation structs (ModerationActionRow, FlagRow, FlagContext): those legitimately include the Agent variant of ModerationTargetType, which this two-variant sum cannot represent. A wider ModerationTarget sum is a separate task.

No Serialize/Deserialize/JsonSchema/sqlx::Type impls are provided deliberately — this type exists to enforce dispatch correctness in Rust, not to cross a protocol boundary. Add impls only when a concrete need arises.

Implementations

impl PostOrCommentId

pub fn as_uuid(&self) -> Uuid

The inner UUID, regardless of variant.

pub fn is_post(&self) -> bool

true if this reference is a post.

pub fn is_comment(&self) -> bool

true if this reference is a comment.

pub fn as_post(&self) -> Option<PostId>

Extract the PostId if this is the Post variant, otherwise None.

pub fn as_comment(&self) -> Option<CommentId>

Extract the CommentId if this is the Comment variant, otherwise None.

pub fn kind(&self) -> ContentKind

Which kind of content this is, for the wire

pub fn kind_str(&self) -> &'static str

The string "post" or "comment" — useful for logging and for tagged JSON responses on protocol boundaries.
