HIR (previously known as descriptors) provides a high-level object-oriented |

| <a href=#3 id=3 data-nosnippet>3</a>//! |
| <a href=#4 id=4 data-nosnippet>4</a>//! The principal difference between HIR and syntax trees is that HIR is bound |
| <a href=#5 id=5 data-nosnippet>5</a>//! to a particular crate instance. That is, it has cfg flags and features |
| <a href=#6 id=6 data-nosnippet>6</a>//! applied. So, the relation between syntax and HIR is many-to-one. |
| <a href=#7 id=7 data-nosnippet>7</a>//! |
| <a href=#8 id=8 data-nosnippet>8</a>//! HIR is the public API of the all of the compiler logic above syntax trees. |
| <a href=#9 id=9 data-nosnippet>9</a>//! It is written in "OO" style. Each type is self contained (as in, it knows its |
| <a href=#10 id=10 data-nosnippet>10</a>//! parents and full context). It should be "clean code". |
| <a href=#11 id=11 data-nosnippet>11</a>//! |
| <a href=#12 id=12 data-nosnippet>12</a>//! `hir_*` crates are the implementation of the compiler logic. |
| <a href=#13 id=13 data-nosnippet>13</a>//! They are written in "ECS" style, with relatively little abstractions. |
| <a href=#14 id=14 data-nosnippet>14</a>//! Many types are not self-contained, and explicitly use local indexes, arenas, etc. |
| <a href=#15 id=15 data-nosnippet>15</a>//! |
| <a href=#16 id=16 data-nosnippet>16</a>//! `hir` is what insulates the "we don't know how to actually write an incremental compiler" |
| <a href=#17 id=17 data-nosnippet>17</a>//! from the ide with completions, hovers, etc. It is a (soft, internal) boundary: |
